Aug 11, 2021Characterizations of Coal-FBT structure and morphology. Milling or thermal annealing transforms the carbon structure; for example, ball-milling of coal leads to partial amorphization and increases the reactivity of carbon. Thermal annealing of coal at about 1000 C releases aromatic C–H groups and randomly associates BSUs face to face [41,42
